I recent got a job lot of retro stuff off ebay and this was buried among the contents of the box. http://imgur.com/a/LdJmP#0 IT appears to be a development board of some kind? does anyone have any ideas as to what it could be? So far the most viable answer |I have gotten is this from a Reddit user "Looks a ton like the inside of an Atari 2600 cartridge - as many have said, it is a dev cart with slots. Actually, some research would suggest that it is a TRS-80 Development kit. [1] This interview suggests that the company printed on it developed the assembly language for the TRS-80, so it makes sense they would also make the development kit. All the CoCo games were written with the Macro-80C assembler package developed by The Micro Works. EDIT: More research would suggest that it is part of the SDS80C Software Development System. The Micro Works has made EEPROM Programmers since the 70s, so it would make sense that their dev kit would include a socketed chipset. I can't find any online pictures of the SDS80C." Is there any way to confirm it as being this? I cant find any images of the SDS80C Software Development System he talk about either. So anyone have an idea or able to confirm it as the SDS80C?
